Using a Formal Parameter to Obtain a Return Value

A function will now be developed which computes a return value based on its formal parameter. Recall from algebra that the expressions and are equivalent. Recall also that logarithms are exponents; specifically, is the exponent to which is raised to get .

From this, the following can be seen to hold true.

One of the fundamental properties of logarithms states that the logarithm of a number raised to a power is equivalent to that power multiplied by the logarithm of the number.

By combining these facets of logarithms, square roots can also be determined using logarithms.

Use the cmath functions pow and log10 to write a function sqrtViaLogs which implements this formula; add it and its prototype to the program. Extend function main with a for loop to use this function to display the square roots of the integers 1 through 9, one to a line; be sure that the index of the for loop, which is being passed to the square root function, is an integer.

I am learning C++ now about void.

Can you write this code not complicated?

Thanks for your help :)
